1) There are 2 sets of ×180MW gas-steam combined cycle power generation units,
which adopt a 1+1+1 (one-to-one) configuration, which consists of a gas turbine, a waste heat boiler,
a steam turbine, a generator and its auxiliary machinery.
The gas turbine is an MS-9001E (PG9171E) , unit manufactured by a division of the American GE Company, and is equipped with a waste heat boiler and a combined cycle dual-pressure condensing steam turbine.
2) The first set of gas-steam combined cycle generating units consists of (#1 gas turbine, #2 boiler and #2 steam turbine) was put into commercial operation on November 9, 2004 (burning heavy oil), and was converted from oil to gas in January 2010. The LNG natural gas power generation operation was completed in November 2010, and the pipeline for natural gas was connected in July 2014. In April 2015, the #1 gas turbine underwent DLN transformation.
3) The second set of gas-steam combined cycle generating units (#3 gas turbine, #4 boiler and #4 steam turbine) was put into commercial operation on December 6, 2004 (burning heavy oil), and was converted from oil to gas in January 2010. The LNG natural gas power generation operation was completed in November 2010, and the pipeline for natural gas was connected in July 2014. In May 2014, the #3 gas turbine completed the DLN transformation work.
